  • For women with risk factors for preterm birth, screening and intervention for sleep disorders may improve outcomes.

Key results

  • Short sleep duration was associated with an increased risk for preterm birth compared with those with the longest sleep duration (relative risk [RR], 1.23; 95% CI, 1.01-1.50).
  • Women with poor sleep quality were at an increased risk for preterm birth (RR, 1.54; 95% CI, 1.18-2.01).

Study design

  • Systematic review and meta-analysis.
  • Studies with sleep duration and quality in pregnant women were identified (10 studies).
  • Preterm birth was defined as
  • Funding: Natural Science Foundation of Liaoning Province.
